One of my little Wyandotte chicks also has some sort of beak deformity.
I found a group on FB that is called Crossbeak Poultry In Motion. They are a no-cull support group that offers education and support for crossbeaked birds including how to tell if they are eating enough.
Maybe you can check there for information on how labor intensive of a task it will be to care for this chick?
You can weigh the chick using a gram scale to document weight, and provide easier to eat foods like wet mash in a deep bowl or tray. Check the crop to see if it is nice and round - an indicator of it being full.
So far we are doing well just providing wet mash once a day and letting it take care of itself. Pics taken 6/27 - getting a little more crooked each day!
